• Describe the role of the systems analyst in the Software Development Life Cycle: A systems analyst is a person who analyses systems, determines requirements and then plans information systems. They are the problem solvers who possess strong analytical and communication skills.

• Understanding the ProblemWhen a system is created their are obviously going to be some problems and issues related to it. This can happen due to an array of things but it mainly happens because of inaccurate data. The project development team for the information system must determine and then solve the problems and issues. At this stage, their should be a a clear problem statement. A preliminary investigation determines whether or not a quick fix can fix the current system, or that a new system must be created. Data should be collected throughout the system cycle. This data should be found so that it is efficient to the cycle by giving it the full potential to understand the problem. The requirement report is a statement that states the needs of a system. It should outline the aims and objectives of the system and how it will benefit the organisation.An Analysis report is carried out by the Sysyems Analyst that examines current processes and procedures in the current system and proposes new processes or updated processes for the proposed new/updated information system.This leads fo a Feasibility Study that assesses all the constraints involved with creating/updating the proposed new/updated information system. The Feasibility report assesses alternative solutions and makes a recommendations after considering the constraints:
  • Technical constraints
  • Operational ( or Organisational) constraints
  • Economic constraints
  • Schedule constraints

• Requirements engineering

• Research an example of a requirements engineering software application.

What's Tom's Planner?

• Tom's Planner, allows you to create and share Gantt Charts online with "drag and drop" simplicity. It has great ease of use and gives control back to the project manager. Watch the quick tutorial or play around with Tom's Planner for free.

• Create schedules with simple drag and drop actions.
• No extensive manual, just a quick 3-minute tutorial <<< Please view this
• No installation required, just hit the 'open tool' link
• Share your schedules online with your team
• Viewing schedules is free, no account needed
• Schedules are saved on your computer: private and secure
• Include schedules in your report as an image

• Planning If the preliminary investigation recommends further examination of a new system, then a project plan must be developed. A project plan organises the project by specifying the:
  • who
  • what
  • how
  • when

• a gantt chart
• schedule for the completion of tasks
• journal
• a funding management plan and
• a communication management plan.
• Information Management Software helps individuals manage information and schedule tasks. It allows email messages to be exchanged and organised.
• Project Management Software contains most of the features of information management software. It is a toll that plans, manages and communicates information efficiently in a large project. An example of this toll is the gantt chart. It gives the organisation an understanding of the timing/schedule of tasks.
